DXS-3350SR Gigabit Layer 3 Switch
The following fields can be configured for GVRP on the Switch:
Parameter
Description
Unit
Select the unit in the stack you want to configure.
From/To
These two fields allow you to specify the range of ports that will be included in the Port-
based VLAN that you are creating using the 802.1Q Port Settings page.
PVID
The read only field in the 802.1Q Port Table shows the current PVID assignment for
each port, which may be manually assigned to a VLAN when created in the 802.1Q
Port Settings table. The Switch's default is to assign all ports to the default VLAN with
a VID of 1.The PVID is used by the port to tag outgoing, untagged packets, and to
make filtering decisions about incoming packets. If the port is specified to accept only
tagged frames - as tagging, and an untagged packet is forwarded to the port for
transmission, the port will add an 802.1Q tag using the PVID to write the VID in the
tag. When the packet arrives at its destination, the receiving device will use the PVID
to make VLAN forwarding decisions. If a packet is received by the port, and Ingress
filtering is enabled, the port will compare the VID of the incoming packet to its PVID. If
the two are unequal, the port will drop the packet. If the two are equal, the port will
receive the packet.
GVRP
The Group VLAN Registration Protocol (GVRP) enables the port to dynamically
become a member of a VLAN. GVRP is Disabled by default.
Ingress
This field can be toggled using the space bar between Enabled and Disabled. Enabled
enables the port to compare the VID tag of an incoming packet with the PVID number
assigned to the port. If the two are different, the port filters (drops) the packet. Disabled
disables ingress filtering. Ingress Checking is Disabled by default.
Acceptable Frame
Type
This field denotes the type of frame that will be accepted by the port. The user may
choose between Tagged Only, which means only VLAN tagged frames will be
accepted, and Admit_All, which means both tagged and untagged frames will be
accepted. Admit_All is enabled by default.
